PROJECT DESCRIPTION:
This project calls for the replacement of 355 feet of 1952 sewer force main that extends
from the Main Beach Sewer Pump Station in Breakers Drive up the slope between two
houses to Ocean Boulevard and then up Marguerite Avenue to the first alley. Instead of
replacing the line in the same location up a steep slope between two houses, an
alternate alignment in Breakers Drive, up the ramp serving Corona del Mar Main Beach
and along Jasmine Avenue was chosen. Even though this alignment is almost 4.5
times longer, it was felt that a standard installation in the street would not be
significantly more expensive and that the new line would be more accessible in the
future for maintenance.
Also included in the project is the replacement of the existing 4 -inch cast iron water
main within Breakers Drive with a new 8 -inch water main. This line was installed in
1938 and relined in 1980. Existing water services and fire hydrants are to be replaced.
The new water line provides increased fire flow protection to Breakers Drive and the
project is recommended in the soon to be completed water master plan.
THE REBIDDING PROCESS
This project is a re -bid from December 2000. On January 9, 2001, the City Council
rejected bids because the cost of the project was higher than anticipated and exceeded
available funding in last year's CIP authorization. In an effort to establish the most
economic alternative, staff added the option of replacing the sewer main in its existing
location within the slope to Marguerite Avenue. Both options were bid during this
current bid process. Schedule A was the original project, which consisted of a new
force main along Breakers Drive. Schedule B considered the option between the
houses and up the slope to Marguerite. The attached bid summary shows the bid
results of the two options. All three bidders showed that going up the slope would be
significantly more costly than constructing the new longer force main in Breakers Drive.
Additionally, staff reconsidered the Breakers Drive repaving options for the waterline
installation to see if some cost savings could be obtained. Breakers Drive is gated and not
open to the public and is maintained by the Breakers Drive Association. The staff has
worked with the Association to obtain a cost sharing agreement to repave the entire street.
The Breakers Drive Homeowners Association will fund half of the repaving efforts or
$13,400. Upon project award, staff will invoice the association for their share.
With the redesign of the pavement and the commitment by the residents for cost
sharing, the City saved approximately $40,000 in cost compared to the bids received
last December.
